"もし主が再び私たちに日光を与え、私があなたに十分な戦いを与えなければ、私はもう二度とあなたに出てきて欲しいと頼まないでしょう"

Simplified Meaning:

Imagine someone promising their friend that they will have fun in the sun if the weather clears up. This person is confident in their ability to deliver a great time but also acknowledges the importance of good conditions, like sunny weather. In a historical context, this could relate to a military leader telling their troops that if they get good weather, they'll definitely take them into battle. It shows a strong commitment to action when the right moment comes. People can apply this idea by making sure they follow through on promises when circumstances are favorable. For example, if a student promises their parents they will study hard once they have the right materials, they must actually put in the effort when they do get those materials. It’s about seizing the opportunity and not letting down those who believe in you.
